Biostat 203B Homework 2 Solutions

Due Feb 7 @ 11:59PM

Use tidyverse (ggpot2, dplyr) to explore the MIMIC-III data introduced in homework 1.

Q1

Demographic information of the patients admitted into hospital is available in ADMISSION.csv. See https://mimic.physionet.org/mimictables/admissions/ for details of each field in this file. Summarize following variables using appropriate graphs:

• admission year
  
• admission month
  
• admission week day
  
• admission hour
• length of hospital stay
  
• admission type
  
• number of admissions per patient
  
• admission location
  
• insurance
  
• language
  
• religion
  
• martial status
  
• ethnicity
  
• death

Note it is possible that one patient (uniquely identified by the SUBJECT_ID) is admitted into hospital multiple times. When summarizing some demographic information, it makes sense to summarize based on only unique patients.

#Admission year bar graph

Solution: Since the admission years are over the span of 100 years, the admissions are about on average 2 admissions per day. According to the training that was done for this class, the data span is actually over 10 years, thus the amount displayed should be 10 times more. On average, the admissions are about 20 per day.

admissions %>%
  mutate(adm_year = year(ADMITTIME)) %>%
  ggplot() + 
  geom_bar(mapping = aes(x = adm_year))

#Admission month bar graph

Solution: The bar graph seems pretty consistent over each month. The average amount of admission per month is about 5000.

admissions %>%
  mutate(adm_month = month(ADMITTIME)) %>%
  ggplot() + 
  geom_bar(mapping = aes(x = adm_month))

#Admission week day

Solution: According to the days of the week, the weekends in the first and last position are much less compared to the week days. Possibly, it could be related to work injuries or the amount of sheer activities that are done on the week days that allow for the admissions to increase during the week days.

admissions %>%
  mutate(wday = wday(ADMITTIME)) %>%
  ggplot() + 
  geom_bar(mapping = aes(x = wday))

#Admission hour

Solution: From the bar graph for the number of admissions per hour, the highest admissions, about 5000, is at the seventh hour. This could most likely mean that there may be the most accidents when people are trying to get to work. Also, at the sixteenth through the eighteenth hour remains consistently high at about 3,500 admissions, which can also mean going back home from work.

admissions %>%
  mutate(hour = hour(ADMITTIME)) %>%
  ggplot() + 
  geom_bar(mapping = aes(x = hour))

#Length of stay

Solution: The length of stay is skewed right, which means that the length of stay do not normally last more than 100 days; there are very few that are about 100 days, but very miniscule. The max peak seems to be around 3-5 days.

admissions %>%
  mutate(los_days = as.numeric(as.duration(DISCHTIME - ADMITTIME) / 86400)) %>%
  ggplot(aes(x = los_days)) + 
  geom_histogram (bins = 100) + 
  labs(x = "Length of Stay (days)")

#Admission Type

Solution: The four types of admission includes: elective, emergency, newborn, and urgent. A little more than 40,000 patients were admitted to the hospital as an emergency, while urgent had the least admissions with about 10,000 admissions.

admissions %>% 
  group_by(ADMISSION_TYPE) %>%
  summarize(count = n()) %>%
  ggplot(aes(x = ADMISSION_TYPE, y = count)) +
  geom_col()

#%>%
 # mutate(freq = N / sum(N),
  #pct = round((freq*100), 0))

#Number of Admissions/Patient

Solution: On average, there are about one to two admissions per patient. There are a few that have major peaks that may have 6-7 admissions.

admissions %>% 
  group_by(SUBJECT_ID) %>%
  summarize(count = n()) %>%
  ggplot() + 
  geom_col(aes(x = SUBJECT_ID, y = count))

#Admission Location

Solution: The highest admission location is the emergency room admit, which is coherent with the admission type. The other types of admission locations usually deal with the transferring from different hospital or referred from elsewhere.

admissions %>% 
  group_by(ADMISSION_LOCATION) %>%
  summarize(count = n()) %>%
  ggplot(aes(x = ADMISSION_LOCATION, y = count)) +
  geom_col() +  
  theme(axis.text.x = element_text(angle=90, hjust=1))

#Insurance sorted by unique values using distinct

Solution: The majority of the insurance coverage of the patients come from Medicare, with private being a close second. Very little of the coverage comes from self pay, government, and Medicaid.

admissions %>% 
  group_by(INSURANCE) %>%
  distinct(SUBJECT_ID) %>%
  summarize(count = n()) %>%
  ggplot(aes(x = INSURANCE, y = count)) +
  geom_col() + 
  theme(axis.text.x = element_text(angle=90, hjust=1))

#Insurance without unique values

admissions %>% 
  group_by(INSURANCE) %>%
  summarize(count = n()) %>%
  ggplot(aes(x = INSURANCE, y = count)) +
  geom_col() + 
  theme(axis.text.x = element_text(angle=90, hjust=1))

#Language

Solution: The majority of the admitted patients tend to speak English with a count of almost 25,000 patients. Additionally, NA was a little higher than English. Most of the languages listed did not have any, there were also very few Spanish speakers, Russian, Portuguese, and a few others.

admissions %>% 
  group_by(LANGUAGE) %>%
  distinct(SUBJECT_ID) %>%
  summarize(count = n()) %>%
  ggplot(aes(x = LANGUAGE, y = count)) +
  geom_col() +
  theme(axis.text.x = element_text(angle = 90, hjust = 1))

#Religion

Solution: The majority of the patients admitted are Catholic, I am a little surprised that Chrisitianity is not a specific option, even though there are options that are branched out from Christianity. This could be a reason patients might choose Catholic, since it is similar in some ways. The other major counts are not specified or unobtainable.

admissions %>% 
  group_by(RELIGION) %>%
  distinct(SUBJECT_ID) %>%
  summarize(count = n()) %>%
  ggplot(aes(x = RELIGION, y = count)) +
  geom_col() + 
  theme(axis.text.x = element_text(angle=90, hjust=1))

#Marital Status

Solution: Marital status is represented by a bar graph. The majority of the admitted patients are married, the second major category are single and not available. It is interesting that there were no counts for life partner.

admissions %>% 
  group_by(MARITAL_STATUS) %>%
  distinct(SUBJECT_ID) %>%

#Graph for icu age of admission Solution: Similar to the graph in question2, the majority of the ICU age of admissions are around 60-80 years old.There are many counts for 0 and some over the age of 300. This could be the range of the ages in the data that were altered for confidentiality.

CHARTEVENTS.csv (https://mimic.physionet.org/mimictables/chartevents/) contains all the charted data available for a patient. During their ICU stay, the primary repository of a patient’s information is their electronic chart. The ITEMID variable indicates a single measurement type in the database. The VALUE variable is the value measured for ITEMID.

D_ITEMS.csv (https://mimic.physionet.org/mimictables/d_items/) is the dictionary for the ITEMID in CHARTEVENTS.csv. Find potential values of ITEMID that correspond to systolic blood pressure, i.e., LABEL contains the string systolic.
